摘要
A novel hyperbranched conjugated chemosensor with bipyridyl groups as periphery groups(BPY-HPV) was synthesized.BPY-HPV was highly sensitive to metal ions(Cu^(2+),Ni^(2+)) for the strong coordination interaction(K_(sv) at the order of 10~7 mol^(-1) L) monitored by fluorescence spectroscopy.Moreover,by hydrogen bonds and charge transfer interaction,BPY-HPV shows strong interaction with 1,1,2,2-tetrachloroethane whatever in CH_2Cl_2(K_(sv)~10~6 mol^(-1) L) or film.
